 BEPI Article Recap:
This year, the Pentagon’s Quadrennial Defense Review-a strategy document that lays out the Pentagon’s vision for its missions and force structure every four years-identified climate change as both a potential source of conflict and a factor in military operations. But the Pentagon building itself, situated in Arlington County, Virginia, is currently undergoing a big green renovation.
The building consolidated 17 buildings of the War Department to cover 29 acres-the largest ground area of any office building in the world.
The building was designated a National Historic Landmark in 1992 and had never undergone a major renovation until the Pentagon Renovation and Construction Program Office, or PENREN, began modernizing the 6.5 million square foot structure a year later. The renovation is currently 80 percent complete and anticipated to be completed three years ahead of schedule in 2011. So far, five renovation projects are LEED certified and the Pentagon Library and Conference Center is LEED silver.
Wedge 1 renovations included blast-resistant windows, removal of hazardous debris and materials, and energy efficient infrastructure design.
Insulated windows and advanced energy control systems at the Pentagon will also cut the building’s monthly $1.1 million electric bill. Cree’s LR24-recessed LED lights would offer a 22 percent energy reduction compared with traditional fluorescent lights, reducing the Pentagon’s carbon dioxide emissions by 140 tons per year.
Additionally, NHRP is now one of the most advanced solar energy systems in the country with 12 advanced features that use solar energy instead of fossil fuels, including a solar thermal tile air heating roof system, photovoltaics beneath solar thermal tiles that generate electricity and heat, and rainwater recovery from the solar roof to supply the indirect evaporative cooling stages.
